DISPLAY APPARATUS.

Specification of Letters Patent.

Patented Dec. 26, 1911.

Application filed March 13, 1911. ,Serial No. 614,245.

To all whom it may concern."

Be it known that I, KIHEI KoIKn, a subject of the Emperor of J apan,.anda resident of the'city of Seattle,'in the county of King and State ofVashington, have invented certain new and useful Improvements in DisplayApparatus, 'of which the following is a specification.

My invention relates to apparatus of the above type wherein a series ofslides or the like are successively moved for the display of theircontents, and removed after a pause of predetermined length, and it hasfor a primary object the provision of a simplified and improvedconstruction and arrangement of parts by which the slides are controlledand operated.

Other objects will be set forth as my description progresses and thosefeatures of construct-ion, arrangements and combinations of parts inwhich my invention resides, succinctly defined in my annexed claims.

Referring to the accompanying drawing. wherein like numerals ofreference indicate like parts throughout the several views: Figure 1 isa vertical longitudinal section of the apparatus. Fig. 2 is a horizontalsection thereof. Fig. 3 is a detail perspective of the adjustableengaging members of the slide shifting mechanism. Fi 4 is a fragmentaryview, with portions being broken away, illustrating more particularlythe circuit closing means for the electro-magnet, and Fig. 5 is aperspective illustrating a sign board equipped with my invention.

Reference numeral 1 indicates an oscillatory driver, journaled on a stud2 of a suitable casing 3, the same being substantially Y-shaped andprovided on its furcations with adjustable fingers or engaging parts 4,adapted to be moved-into and out of the path of a series of slides 5, byand during movement of the driver 1, as hereinafter v more fully setforth.

For oscillating driver 1, I conveniently provide a spring 6 and anelectro-magnet .7, the former serving to return driver 1 to its firstposition wherein it is connected with the slides 5. Electro-magnet 7 isconnected by wires 8 with a suitable source of electrical energy, in oneof which wires I interpose a switch 8*, the latter being pivoted at 9 ona fixed internal support 10 of easing 3 and provided with a contactconnected through a binding post 11 with a section of one wire 8 andadapted to be moved into and'out of. engagement with an underlyingcontact, provided on support lO and having a binding post 12 with whichthe second section of the last named wire 8 which leads to magnet 7, isconnected, see Fig. 4.

Reference numeral .13 indicates an armature for magnet 7, the sameextending vertically from the stem or rearwardly pro- 5 jecting portion1 of driver 1. Adjustable fingers or engaging parts 4 are connected forsimultaneous movement by a bar 14 having a depending follower 15 adaptedfor travel in a cam groove 16', formed in support 10. While connectionbetween fingers or engaging parts 4 and the branches of driver 1 vcan beotherwise efl'ected, I prefer to provide the fingers 4 .with 'aperturedlugs 16 which slidably receive the adjacent end por-' tions of saiddriver branches.

Reference numeral 17 indicates a, track, supported in casing 3 bysuitable bracket arms 18, said track extending concentriso cally aboutstud shaft 2 for supporting slides 5 for movement between a source oflight 19 and projecting lens 20.

Slides 5, which are of glass or other suitable-transparent constructionare mounted in carriers 21 having track engaging parts 22, convenientlyin the form of hook shaped extensionsthereof and each provided with anupwardly projecting pin or engaging part 23, positioned to besuccessively engaged by fingers 4, whereby through such engagement onefinger will position a car- 'rier for the display of its contents andthe other finger will remove such carrier during the next correspondingmovement of driverl. V

Assuming that the parts are arranged as shown with switch- 8? adjustedto close the electrical circuit, armature 13 is drawn towardelectro-magnet 7 thereby swinging driver 1 to simultaneously move onecarrier 21 from between lamp 19 and lens 20, and

the succeeding carrier to such position of display. During this movementof driver 1, follower 15 travels in cam groove .16, which issubstantially elliptical in form, and Withdraws fingers 4 from theengagingparts 23. Movement in the reverse direction is effected throughsprin 6, the latter operating when magnet is deenergized through openingof switch 8. Switch 8 is operated by driver 1 whose stem 1- alterme tomaintain a multiplicity of slides, constituting a supply, on acomparatively short length of'track.

In Fi 5 I have illustrated my invention provided in'connection with asign board 25 for illuminatingthe face thereof, and when so employed-Ipreferably provide slides 5 in different colors.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States of America, 1s:

1. A display apparatus comprising a track, a slide carrier mounted onsaid track, a driver supported for movement, a relativelyinovableengaging member on said driver, means for alternately projectingand retracting said engaging member by and during movement of saiddriver to thereby connect and release said slide carrier, and means foroperating said driver in relatively opposite directions.

2. A display apparatus comprising a track, a plurality of slide carriersmounted on said track and provided with engaging parts, a rotatablysupported driver, means for operating said driver, relatively adjustablemembers on said driver spaced one in advance of the other tosimultaneously engage the engaging-parts of respective slide carriers,and means for projecting and retracting said nembers during movement ofsaid driver.

3. A display apparatus comprising a track, a plurality of slide carriersmounted on said track and provided with engaging parts, a rotatablysupported driver, means for operating said driver, relatively adjustablemembers on said driver spaced one in advance of the other tosimultaneously engage the engaging parts of respective slide carriers,and means for projecting and retracting said members during movement ofsaid driver,

' said last means comprising a cam track providedon a relatively fixedpart, and a follower carried by said adjustable members and engaged withsaid cam track.

4. A display apparatus comprising a'track,

a plurality of slide carriers mounted on said track and provided withengaging parts, a

rotatably supported driver, means for operating saiddriver, a pair offingers slidably supported on said driver for outward movement withrespect to its axis, said fingers being connected for simultaneousmovement, and means for projecting and retracting said members duringmovement of said driver.

5. A display apparatus comprising a track, a slide carrier mounted onsaid track, a driver rotatably supported, means for alternatelyconnecting and releasing said carrier with respect to said driver,electro-magnetic means for operating said driver, and means operated byand during movement of said driver for .deene'rgizing saidelectro-magnetic 4 means.

6. A display apparatus comprising a track, a slide carrier mounted onsaid track, a driver rotatably supported, means for alternatelyconnecting and releasing said carrier with respect to said driver,electro-magnetic means for operating said driver in one direction, othermeans for operating said driver in the reverse direction, and meansoperated by and during movement of said driver for controlling said lasttwo named means for alternate operation.

7. A display apparatus comprising a track, a slide carrier mounted onsaid track, a driver rotatably supported, means for alternatelyconnecting and releasing said carrier with respect to said driver,electro-magnetic means for operating said driver in one direction, aswitch for controlling the flow of current to said last means, a springfor operating said driver in the reverse direction, and means wherebysaid switch is opened and closed by and during movement of said driver.
